This high quality, sturdy foam board is specially designed for easy cutting and to produce clean, sharp edges. It has a number of uses, including mounting, backing artwork, making models and framing. All of the boards come in multi-packs of between 10 and 25 foamboard sheets (depending on your chosen size), meaning that just one pack can fulfil multiple purposes. Made by the reliable brand Westfoam, this board is made of three components – the foam core is covered with acid-free paper for a smooth surface and increased longevity. At 5mm thick it is both rigid and durable, but not overly bulky or heavy.
